T all whom it may concern: f 7 Be it known that we, EDMnND NOLAN and CHARLES W. WVALTnns, both citizens of the United States .o'lE'KAfmerica, troit, in the county of Michigan, have invented certain new and useful Improvementsfin Grease-Gun Fillers,

of which the following is a specification,

v reference beings had therein to the accom 10 panying drawings.

This inventlon' relates to grease gun fillers, V and it is theobject "ofthe invention to"pro- Vmembers is thus subjected to a compression, the efi'ect'of which isto eliminate any. air

' 'vide a device'that will quickly introduce a compact mass of spaces in said mass. embodiment otthe invention is hereinafterdescribed and is illustrated in the accompanying drawing wherein:

Figure l is aview of the grease gunfiller in side elevation; 1

Figure 2 is a similar view show ng the pivotally j connected complementary barrel members swung apart for filling;

r A preferred Figure 3 is a top view, of parts/as shown in Figure" 1. v 4 V In these views the reference "characters A and A designate a pair'of'complementary semi-cylindrical members forming a barrel adapted .to be filled withgrease.

of diametrically opposed lugs B embracing the corresponding end of the member A and pivotally connected to the latter as indicated at C. lhe member A is forme with an integral upward extension D, the

upper end of which is bent throughsllbstan- I tially right angle to form a handle E. The member A is likewise formed with an integral upward extension, the lower portion 40 F of which extends atanupward inclination acrossthe axis ofpthe barrel A, A, said extension terminating in a handle G below and spaced from the handle Within'the barrel A, A a piston H is adapted to reciprocate, said piston being secured to the lower end of a rod 1 having ment with the part F, and having at its upper end anactuating knob or head J. A spring K coiled upon the rod I is compressed between the head ,J and part F during the latter portion of the downward stroke of said rod and functions tomaintain the rod it and piston normally partially raised.

' In the use of the described device, after and piston H have been adjusted residing at De- Wayne and State of grease nto a grease guns sure is now ap The memflberA is formed at its upper end with a pair guiding engageto their" upper limiting position shown Figure 1, the operator by means ofthe handles E and Gswings the barrel members A, PA- .to their divergent positionsshown in Figure 2. The barrel of the device is then,

thrust into a mass of grease so that; the

latter enters and substantially fills the'b'arrel. The handle members E and Gr are then firmly gripped to adjust them 5 into proximity and to shift'the members A and A" slnto" their parallel and-abutting relation shown in Figure 1. The grease between said spaces, and to insure'retention'within the barrel of its contents when the device is withdrawn from themass of grease." 'Pres I plied to the knob J "by the thumb of the hand which is gripping the handles E and G and the piston H is thus actuated to the lower portion of the bar-e rel, extruding the grease which may be re-- ceivedby' a grease gun, grease cup, or any desired receptacle. I 7

1t isa highly desirable feature of the invention that thegreaseis (allowed tofreely enter the barrel when the latteris-initially "introduced into "the mass of grease,-'the divergent relation ofthe barrel members permitting a ready displacement ofair which otherwise would be trapped between the entering g'reasefand the piston and resist complete filling of the'barrel. Also eliminad' tion-fof any air spaces in the mass of grease is fully assured, first, by the compression to V which the contents of the barrel are subjectedwhen the parts A, A are adjusted from a divergent to a parallel relation, and second, by the pressure to jected during ejection by the piston It is to be observed that the'handles and E are so arranged asto be conveniently gripped and pressed'toward each other by one hand of the operator, the piston H being operable by the thumb of the same hand, while the other hand is freeto hold the grease gun or grease cup which is to be filled.

What we claim as our invention is:

which the mass is sub 7 1. In a device of the character described,

the combination with a receptacle comprising a pair of complementary pivotally con nected members forming a barrel,'of handles carried by said members for relatively. adjustingthe same angular-1y, a piston recipe rocatoryinsaid barrel, actuating means tor I said piston in a v A. In a device of the character described, v

reciprocatory within said barrel, an

of the barrel, one of said extensions havin said piston having guiding engagement with one of said members :and resilient means for normally maintaining said actu' ating means in a predetermined position.

2. In a device of thecharacter described, the combination with a pairof complementary pivotally connected members forming a barrel, of integral extensions from said *members at one end of the, barrel terminally forming handles for relatively adjusting said members, apiston reeiprocatory within said barrel, a rod for actuating said piston I having-guiding engagement with one of said extensions and elastic means for normally maintaining said piston in a predetermined position.

3. In a device of the character described, the combination with a pair of complemen-' tary barrel forming members pivotally con-.

nected atone end of the barrel, of handles for said members at saidend of the barrel, a

piston reciproca-tory within the barrel, ac tuating means for said piston having guiding engagement with one of'said'members and aresilient element for normally holding predetermined'position.

thecombination with a pair of complementary barrel-forming members pivotally connectedat one end of the barrel, of a piston ing rod for said piston, extens ons fromsaid members at sa d end a portion crossing the axis of the barrel and forming asllde guide for sald rod.

rithecombination with a .pair of complementarypivotally connected barrel forming members, of a piston reciprocatory within members one of tar'y j barrel forming connected at one end I members, of a actuatand handle forming said members, an actuating rod for said piston projecting beyond one end of said members, handle forming extensions from said which has a portion formfor said rod, and a, spring rod and abutting against ing a slide guide coiled upon said said extension tending to retract the piston.

6., In a device of the character described, the combination with a pair of complemenmembers pivotally of the barrel, of'a pair of integral extensions from said members atsaid end of the barrel terminally and adjacently bent to ointly form a handle grip, a

piston slidably mounted within said barrel means for movforming members, actuating ingsaidpiston forward, and meansfor automatically returning sald piston to its original position.

tary barrel forming members'pivotally connected at one end of the barrel, of apair of integral extensions at one end of saidmemg- .bers terminally bent to form parallel"grip ping portions in a plane-transverse to the axis of said barrel. r

In testimony whereof we afiix our signatures.-
